  • Abstract In this thesis we first present a novel Padding Block Based Distributed Video Coding (PB Based DVC) paradigm. Based on this new DVC coding technique, we then propose a new wireless video transmission network architecture, which combines our proposed Padding Block Based Distributed Video Coding, Digital Video Transcoding (DVT) and Decoding-Friendly Encoder Design (DFED). In this new proposed video transmission network, the DVT is worked directly with the DFED, which is quite different from the conventional DVT, and the DFED is known to have the advantage of simple and efficient decoder. Also, our proposed Padding Block Based DVC solution requires lower computational complexity (CC) and hardware cost at the encoder side, compared with the conventional DVC schemes. In fact, it uses pad blocks and pixels at decoder from reference frame for those skipped blocks at encoder with sum of absolute differences (SAD) and DC classification. Hence, with the new proposed video network configuration, we could further shift the CC from the portable device to the network side, and this enables us to lower the cost of portable device. The experimental results for the uplink path show that the proposed scheme can achieve desired video quality and outperform the conventional DVC schemes for most test video sequences.
